Machine for thinning flowers in gardens
02.05.2024
In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers.

Advanced Infrared Microscope
02.05.2024
Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>
Air trap for insects
01.05.2024
Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>
| Random news from the Archive D-Link DCS-8325LH Cloud Wireless Camera
23.02.2021
D-Link has introduced a new DCS-8325LH cloud-based Full HD wireless camera with support for artificial intelligence technologies. The device is designed for round-the-clock remote audio and video monitoring in home and office video surveillance systems.
The DCS-8325LH is equipped with intelligent video analytics to reduce false alarms, and a human body detection mode to ignore indoor pets.
The camera has a high degree of image detail - 1080p up to 30 frames / s. It has wide viewing angles: horizontally 126°, diagonally 151° and allows you to conduct round-the-clock video surveillance in conditions of limited illumination due to the use of infrared illumination up to 5 m.
It is possible to notify about events in the surveillance area, detect movement in a given area (window, doorway), when crossing an established line, entering or exiting the surveillance area, etc. There is also a built-in microphone and speaker for remote communication. The device supports the WPA3 Wi-Fi security standard.
Events can be recorded to the cloud or to a microSD card up to 256 GB.
The camera complies with the ONVIF network video device interoperability standard and can be used in video surveillance systems using equipment from various manufacturers.
The suggested retail price is $109.
